fixed bug with laser passing between two diagonally placed DF polarizers

This reverts commit f00dbcf8.

The behaviour "fixed" in the above commit as being a bug is in fact
the correct and intended behaviour, as Deflektor style polarizors are
to be treated as solid, tile-filling blocks, not as tiles with a
little bit free space around them, as suggested by the graphics (and
as it is the case with the Mirror Magic variant of these tiles).
